How do you write an equation in slope intercept form given that the line passes through the points (4,1) and (2,-3)?
First we have to find the slope of the equation. To find the slope we have to do;
The main formula of a line is;
We should use one point to find the real equation. If we use (4,1) point;
a is the slope of the equation, we found that as
So the equation of the line will be;
We can check if our equation is right or not with other given point;
So the equation is correct :)
